#1. Telco says the switch is a 5ESS. If we configure the DSP's for 5ESS we intermittently lose the D-channels. Telco says that even though it's a 5ESS switch, the PRI's are configured "standard" or "national" and that we should set the Total Control for NI2. Is this normal/correct? Set it up for NI2 and D-channels appear stable and it answers calls.
NI-2 is correct and normal. Its basically a standard protocol that all (or nearly all, anyway) switch types can use, rather than the proprietary 5ESS, DMS-100, etc. types that are switch specific.
#2. Telco says that even though each PRI has it's own D-channel, that each PRI is configured as it's own single-PRI NFAS group with Interface ID 0. It seems to answer calls whether I just configure for FAS or if I config for NFAS assigning a different NFAS Group to each DSP. Does this matter at all? Seemed kinda wierd, but I haven't worked with PRI's that much.
I don't think it matters.
#3. All 10 PRI's are in a single "hunt group" with 4 different numbers assigned to that group. Regardless of the phone number I call, the call comes into the first DSP. If I busy-out that first DSP, dialing any number results in a busy-signal. In other words, if one DSP is not there, calls don't roll over to the next available PRI. I'm pretty sure this is a telco config issue - but is there something I may be doing wrong? Just want to make sure.
How are you busying them out? If you just busy the modems out and not take the B channels out of service, this is normal. Take the B channels out of service and your calls should roll over correctly. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456
